Xu Mang feels that it is understandable that everyone is not optimistic about graphene. Although many people believe that graphene may achieve room-temperature superconductivity, there are many theoretical data that support this statement.

but

Judging from the graphene superconductivity experiment of Foot Pot Chicken, it is almost impossible for graphene to become a normal temperature superconducting material. The concept of minus 269 degrees has completely destroyed its practical value. This experiment only shows that graphene has

It's just superconducting properties.

The challenge Xu Mang faces now is how to obtain superconducting properties in different ways.

"What's wrong?"

"Look at how restless you are." After dinner, Yang Xiaoman was lying in Xu Mang's arms. She had just read a Weibo post and saw Xu Mang's frowning face. She asked curiously: "Yes?"

Are you worried that the cow that blew out will fall and be crushed to death?"

"no."

"I'm thinking about the sandwich double-layer graphene compound of Foot Pot Chicken." Xu Mang said: "Inserting calcium atoms between the double-layer carbon atom graphene films has actually achieved superconductivity, although it requires 269 degrees below zero.

It just takes time.”

"What is this compound called?" Xu Mang asked.

"c6cac6!"

"Yes, yes!" Xu Mang nodded: "Is it related to the calcium atoms?"

Yang Xiaoman said seriously: "You idiot, you only read half of the paper? The latter research team inserted lithium between double-layer graphene to replace calcium. As a result, no superstructure occurred in the lithium interlayer compound.

guiding phenomenon.”

"ah?"

"Is it caused by calcium atoms donating electrons to the graphene layer?" Xu Mang asked in surprise.

Xiaoman shook his head: "How do I know? Why don't you go back to the laboratory now and test the data to verify your conjecture?"

"good"

"What a ball!" Xu Mang started talking, noticed Xiao Man's expression, and hurriedly changed his words: "I left such a beautiful girlfriend at home without hugging me, and ran to an empty laboratory alone. I'm mentally ill.

?”

The words fell,

Xiaoman was satisfied.

"I think research and theory to find out the physical properties of superconducting graphene is what we need to do now." After a day of training, Yang Xiaoman accumulated a lot of knowledge in this area and educated Xu Mang: "

We can make metallic compounds, or try to change the number of graphene layers, and miracles may happen."

Change the number of layers?

Yang Xiaoman's words provided Xu Mang with different ideas. Of course, all this requires clarifying the nature of superconductivity.

night,

Arriving silently.

The situation was similar to yesterday. Yang Xiaoman felt inexplicably irritable. Xu Mang felt that as time continued to decrease, Yang Xiaoman's irritability index would rise a little more every night. If calculated in this way, by the New Year's Eve

At night, Xiaoman will explode on the spot.

"well?"

"What's going on with you?" Xu Mang looked at Xiaoman's happy face in his arms, and suddenly had a headache, and said, "Are you looking forward to it so much?"

"You take care of me!"

"You idiot, have you ever had a girlfriend before?" Yang Xiaoman said squeakingly: "How many have you had? To what extent?"

Wait a moment!

Routine, trap, trap!

I deliberately dug a big hole and let myself jump into it.

cut!

"No!"

"I am a very pure person. Unless you lean on me desperately, I usually don't talk to girls." Xu Mang said seriously.

Hearing Xu Mang's words, Yang Xiaoman was very angry. What does it mean to lean on you desperately? Who was behind you in the first place? Who kept doing little tricks? Isn't this just to attract my attention?

"Ouch"

"Say what you say!" Yang Xiaoman urged: "I won't be angry."

Not angry?

hehe

How many girls have said to their boyfriends that they would not be angry, but the boys said it and became angry after saying it.

"Really not!"

"I really only have you as my girlfriend. I was alone before. Just think about it. Who would be willing to be friends with me when we were in school?" Xu Mang sighed: "After all, I am so handsome, they will feel pressure.

of."

Ouch!

I really want to beat him to death!

Yang Xiaoman originally wanted to beat him up and came up with a reason to be invincible, but inadvertently this reason became his stepping stone.

"handsome!"

"You're so handsome!" Yang Xiaoman rolled her eyes: "Carry me upstairs, I'm going to sleep!"

Fortunately, Xiao Man was very light, so Xu Mang carried her up the stairs in a princess hug.

The voice is very soft,

The movements are small,

However, Xu's mother opened the door and saw this scene. Her son was holding his daughter-in-law, looking sneaky. Looking at the expressions of the two of them, his son's face was full of nervousness, and his daughter-in-law buried her head in her arms.

, looking from the side, his face looks extremely red!

"Ahem!"

"Be careful at night."

The words fell,

Xu's mother walked down the stairs and went to the kitchen not knowing what to do.

""

""

The two of them were embarrassed.

"What's the ink stain?"

"Are you still going to wait for mom to come up and say something else?" Yang Xiaoman raised his head and glared at Xu Mang: "Hurry up and open the door!"

hastily,

Xu Mang and Xiaoman came to the room and locked the door behind their backs.

this night,

Still so frustrating

The next day,

Back to the lab.

Xu Mang started the next experiment.

With the help of the quantum database, we roughly figured out the superconducting problem of c6cac6. As expected, it is caused by calcium atoms donating electrons to the graphene layer.

"What's wrong?"

"Have you encountered any problems?" Yang Xiaoman saw Xu Mang frowning, stood up and rubbed the corners of his eyes for him, and said, "Frowning for a long time will cause crow's feet."

"I think"

"You said that graphene is a hexagonal honeycomb lattice planar film composed of carbon atoms. It is a two-dimensional material with a thickness of only one carbon atom, but it can achieve superconductivity with calcium atoms sandwiched in the middle. What does this belong to?

What's the situation?" Xu Mang asked: "There is no change, just a layer of calcium atoms."

""

"I don't know either." Yang Xiaoman said, "But we know that there are many ways of superconducting graphene."

"What do you think I should do now?" Xu Mang asked.

"We have to look for answers from other high-temperature superconductors," Yang Xiaoman said: "Observe the superconducting properties of other superconductors and the changes in the quantum microscopic world."
